What this shows Access's Innovation Score is 38.4/100 (top 41% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Access?

Each dot is one of Access’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Access’s own 11.9 claims/patent is at or below the 19.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Access's grants concentrate

Access Bio, Inc. is a focused PatentsView assignee: 7 CPC subclasses with 63.6% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2015 (3 grants) versus a trough of 1 in 2018. By volume, Access sits between AZ, LLC and AcelRx Pharmaceuticals, Inc..

Access's three-year grant acceleration

Access Bio, Inc. shows 2 grants in 2022–2024 against only 0 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
